The document linked details the licensing requirements but does not explain how the O/S handle the individual cores. On my 2650 with 2 dual core processors both msinfo32 and the performance tab of the task manager show 4 processors, what would it do with 2 Quad core processors (if it supported them).
I recently rebuilt my test SBS server with a quad core and got a warning during installation that SBS only supports 2 processors, by the definition of the document I only had one. In my example from NCR the processors were on separate boards, 4 per board and the specially written HAL treated each board as a single processor. Does the standard HAL team 2 cores as one processor or do half of them become redundant?
The 2650 doesn't support dual core processors. You're seeing hyperthreaded processors.
SBS supports 2 processors. So if you were running quad core processors, SBS would support 2 quad cores, yielding 8 cores.
The HAL doesn't care if you're running 2 cores or 32 cores. The OS may limit how many processors (not cores!) the OS can see, but the HAL doesn't 'care'.

The standard version of W2K3 R2 SP2 can use up to four quad core processors. Microsoft's license is based on processor not the number of cores.
